statesman writes: The Associated Press reports that teens who text frequently are three and a half times more likely to have sex. A survey of 4,200 public high school students in the Cleveland area found that one in five students sent more than 120 text messages a day or spent more than 3 hours a day on Facebook. Students in this group were much more likely to have sex. Alcohol and drug use also correlate with frequent texting and heavy Facebook use.
